FRlNGE-KNOTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,413, dated July 13,1897.

Application filed March 11, 1896. Serial No. 582,813. (No model.)

T0 all whom it may concern:

Be it known that I, CLARENCE W. ARNOLD, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Fringe-Knottin g Machines, of which the following is aspecification.

The object of my invention is to construct a machine for knotting fringewhich has been previously woven having a head and depending strands. Itwill be understood, however, that my invention may be combined with amachine for weaving the fringe without departing from my invention.

In the accompanying drawings, Figure 1 is a plan view of my improvedknotting-machine. Fig. 2 is a side view. Fig. 3 is an end view lookingin the direction of the arrow 1, Fig. 1. Fig. 4 is an end view lookingin the direction of the arrow 2, Fig. 1, with the belt-wheels removed.Fig. 5 is a sectional plan view to illustrate the needle mechanism. Fig.6 is a transverse section on the line 6 6, Fig. 1. Fig. 7 is atransverse section on the line 7 7, Fig. 1. Fig. 8 is a longitudinalsectional View on the line 8 8, Fig. 1. Figs. 9 to 20, inclusive, arediagram views illustrat ing the method of forming the knot.

I will first describe the operation of the machine in general.

The fringe having the head and the depending loose ends is fed to themachine and under the heading-clamp, at which point it is combed out soas to present the loose ends to the separator in such a manner thattheywill be parallel with each other and at right angles to the heading.The selector separates a number of the loose ends according to thenumber required for the bunch and feeds them independently to theknotting mechanism,wl1ich consists of a needle and rod around which thestrands are twisted and a hook which draws the strands in such a manneras to form the knot. After the knot is formed the heading is movedforward so that the selecting mechanism may engage another series ofloose ends. The feeding mechanism for the fringe grips the heading afterits loose ends have been knotted.

I will now describe in detail the construction of the apparatus.

A is the frame of the machine.

A is the combing-table, secured rigidly to the frame. The fringe passesover the table to the knotting mechanism. The table has a flange aacting as a guide for the head of the fringe, and secured to the flangeis a clamp-block a, which rests upon the heading, and between the blockand a stud on the flange a is a spring having sufficient tension to keepthe fringe in place during the combing out, select-ing, ancfkhottingoperations. The presser and combing table extends to a point on a linewith the knotting mechanism, so that the fringe is held rigidly untilknotted.

B is a cam-shaft, (clearly shown in Fig. 2,) and extending the fulllength of the machine and on this shaft are the several cams foroperating the several independent elements of the machine. Thiscam-shaft is driven by gearing b b from the driving-shaft B, having fastand loose pulleys 12 b and on this shaft is a hand-wheel 11 so that theoperator can turn the mechanism by hand when necessary. Thedriving-shaft is hollow in the present instance and adapted to a studsecured to the frame of the machine.

On the opposite side of the machine. are brackets c c, in which ismounted a fixed shaft 0, and pivoted to this shaft is a frame 0', whichextends to the combing-table, and pivoted to the frame 0 is a comb-frameC extending over the table A. On the end of this frame are a series ofteeth forming the comb and which engage with the loose ends of thefringe and draw them out in a direct line from the heading-clamp.

The frame 0 is connected to a crank 12 on the cam-shaft B by aconnecting-rod 0, so that as the cam-shaft revolves the frame will havean oscillating motion.

Mounted on the combing-table A is a camlever 0 and this lever is sopivoted that the end 0 will normally rest upon the table, and on thecomb-frame C is a pin 0 which extends in the path of its lever, so thaton the forward motion of the comb-frame it will ride over the lever andloose ends of the fringe and will come in contact with the fringe nearthe heading, and on its return the comb will engage the loose ends anddraw them out. As the comb returns its pin comes in contact with a cam con the combing-table and will have a motion which will move it towardthe knotting mechanism as it is drawing back, so that it will pull thefringe in a direct line, as the feeding mechanism for the head is actingat the same time. Thus anew series of ends is presented to the selectingmechanism.

The comb-frame is returned to its normal position by a spring 0 Fig. 1,as soon as the pin 0 passes the cam 0 the spring retaining thecomb-frame in the normal position, so that it will pass over the lever Con its forward stroke. 7

I preferably rib' the under side of the camblock a as well as the tableunder the clampblock, so that the fringe will be held rigidly whencombed, separated, and knotted. The clamp-block is held to the flange aby screws adapted to openings in the flange, so that while the block isfree to move vertically it cannot move away from the flange.

Mounted in bearings on the frame is a shaft D, having a rotary brush Dat the end, directly above an extension a of the table. This shaft D isdriven from the main shaft by a chain d passing over the sprocket-wheeld and over a sprocket-wheel d on the shaft D. Thus this shaft is drivenat all times, so that the loose ends as they are combed are passed underthe brush and kept in line to be separated and knotted. The end of thecomb c is reduced, so as to pass between the brush and extension a onits return movement. The comb passes over the brush in its forwardmovement.

D D are feed-wheels for the fringe. The heading passes around the wheelD and between it and the wheel D and these wheels are mounted on shaftsD D having their bearings in the frame of the machine, and the wheel Dhas a ratchet-wheel d engaged by a pawl (1*, moved forward by a cam 13on a cross-shaft B driven from the cam-shaft B by bevel-wh eels b 11 Thepawl d is returned by a spring d, Fig. 5.

' Engaging with the ratchet-wheel d is a stoppawl cl to prevent thewheel from turning,

backward. The shaft D is geared to the shaft 1) by wheels 01 (1 Thus thefeed is so timed that it will be intermittent and will take place duringthe time of combing out the loose ends of the fringe, the knottingmechanism being free during this interval, so that a new set of endswill be presented.

The lower shaft D is loose in its hearing, so that its wheel D will bekept in contact with the wheel D by a spring (1 coupled to the shaft;but in case the heading should be increased in thickness at a point thelower shaft will yield and allow the heading to pass without affectingthe working of the machine.

I will now describe the mechanism for forming the loop in the loose endsof the fringe.

Referring to Fig. '7, E is the needle-carrier, pivoted to the fixedshaft E, situated under the cam-shaft B. This needlecarrier has aprojection c on which the cam 2 acts. This cam is secured to the shaftB, so that the needie-carrier moves toward and from the head,- ing ofthe fringe.

E is a sleeve adapted to the bearings e of the carrier, and thissleevehas a screw formed on its exterior surface against which acts the arm F,pivoted at f to the arm 6 of the car-' rier E, and has a projection facted upon by the cam 3. This arm has a movement in the same directionas the needle-carrier E, but moves at a different time. On the movementof this arm the needle will turn so that its hook will engage the looseends of the fringe and partly form the loop.

The needle proper, E has a hooked end 6 and is carried by the sleeve E,but has a movement within the needle and sleeve, as shown clearly inFig. 7, so as to close the hooked end, andthus allow the needle to drawthe loose end of the fringe through the formed loop and thus completethe knot. This latch is limited in its movement by a pin or screw 6,adapted to a way 6 in the sleeve E and the spring e tends to retract thelatch. The latch is moved forward by a lever E also pivoted to the shaftE, and this lever has a projection 6 which is in the path of the cam 1.The end of the lever E acts upon the end of the latch e and, asindicatedbyits cam,closes the hooked end of the needle during a certain time inthe formation of the knot.

A spring 6 tends to keep the lever E* in contact with its cam,while thespring a, which is attached to an arm e of the carrier E, tends to keepthe carrier in contact with its cam, while the spring (2 tends to keepthe arm F against its cam.

The needle is turned in one direction by a spring a, which is connectedto the arm e and has a cord e which is wrapped around the shank of thesleeve e so that while the 1 arm F turns the needle in one direction thespring retracts it as it is released by the arm.

.G is a frame mounted under the table A, and adapted to bearings on thisframe is a shaft G, having at one end the selecting-pin G The frame isso acted upon by cams that its pin will select the number of loose endsto be tied together in the knot and will carry them over the projectedneedles, so that they will be engaged by the hook of the needle when itis retracted before it is turned.

The frame G has two movements, one alongitudinal movement and the othera movement toward and from the heading-guide. The latter movement isaccomplished through the medium of the cam 9 on the shaft 13 acting upona rod g, pivoted to the forward end of the frame G. The longitudinalmovement of the frame G is accomplished by the cam b on the camshaft13*, which acts upon the lever g, pivoted to the frame of the machine,and connected to the frame G by a connecting-rod The selecting-pin G ismounted on the shaft G, which is actuated by acam l0, acting against arod g connected to alever 9 on the shaft G, so that the selectorpin israised and lowered at the proper time.

Suitable springs keep the rods 9 and g and the lever g against the cams.Thus as the brush D rotates it brushes out the loose ends of the fringethat pass from the comb, and the selecting-pin selects a number of theloose ends and draws them over the needle which has moved forward.

H is a reciprocated rod, and this rod has at its end a channel h for thereception of the point of the selector-pin G so that when the loose endsare drawn over this bar the selector-pin can move a portion of the loopto one side of the needle so that the ends will be in the hooked portionof the needle. The rod H is moved longitudinally by a cam h on the wheelZ). This cam acts against the lever 72/ pivoted to the frame of themachine, and this lever engages the rod and tends to draw it away fromthe path of the needle. A spring 7L3, connected to the rod, tends tokeep the lever 77/ in contact with the cam.

I is a friction-hook, which engages the series of ends and carries themover the rod H and into the hook of the needle, the presserbar holdingthe threads in such frictional confact with the hook that they cannotbecome accidentally detached from the hook, but must be drawn out of thehook by the needle as it is drawn down. The friction-hook is carried byan arm I, which is secured to a shaft 1 adapted to bearings on the frameof the machine. The arm extends beyond this shaft and is connected by arod i to a lever 1 pivoted on a stud 2", projecting from the frame ofthe machine, and the opposite arm of this lever is acted upon by a cam Aon the shaft 13. A spring 2' tends to keep the lever in contact with itscam. The shaft 1 has also a longitudinal movement so as to bring thehook I near the path of the needle. This is accomplished by a cam t onthe cross-shaft 3 acting on the lever 1' spanning the shaft 1 so thatthe hook not only has a movement toward the fringe, but has alongitudinal movement as well.

J is a spreader for separating the selected ends from the balance thatremain under the control of the brush,and this spreader has a motiontoward and from the fringe and is carried by a sleeve J, mounted on theshaft K. This sleeve is adapted to bearings on the frame of the machineand has an arm J acted upon by a cam 5. A springj tends to keep the armJ against the cam.

K is an arm having the same movement as the arm J, but actuated by a cam6, through the medium of the shaft K and arm K the sleeve J beingpartially cut away to permit of the attachment of the arm K directly tothe shaft K, so as to have a movement independent of the arm J. A springtends to keep the said arm against the cam. The arm K forces the knottedends down out of the path of the needle after they are formed, so thatthe knotted bunch will not interfere with the forming of the succeedingknot.

M is a presser-lever,which holds the loose ends of the fringe againstthe needle as it is drawn down and after the ends are drawn from thefriction-hook, this lever moving with the needle until the knot isformed.

The movement with the needle is accomplished by a cam '7 on the shaftB,which acts upon the lever M, hung to the shaft E, so that it can slidelongitudinally thereon. A spring m returns the lever and keeps it alwaysin contact with the cam. The presserlever has a head mflwhich pressesagainst the ends at the hook of the needle and is forced against theneedle by a cam 8 on the shaft B. This cam acts upon a lever M, pivotedat m and connected to the lever M by a rod m The pressure is withdrawnby a spring m Referring to Figs. 9 to 20, inclusive, the knot is formedas follows: The loose ends of the fringe are combed and brushed out andthe heading, with its fringe, is fed forward. The needle then moves upto the position shown in Fig. 9 and the selector-pin Gr selects a bunchof ends from the fringe and then moves across the path of the needle, soas to place the ends across the needle to be engaged by itshook.ThebrushD,rotatingcontinuously, keeps the ends always under tension. Thespreader J enters the space between the selected ends and the unselectedends, so as to make a positive separation. The hooked needle thenretracts and its hook engages the strands laid across the needle by theselectorpin G, as shown in Fig. 10. The needle then makes a full turn tothe right,wrapping the strands around its shank, as shown in Fig. 11,and moves forward again, so that its hook will be out of the way. Therod H is then projected over the needle and assumes the position shownin Fig. 12. The friction-hook I then moves forward from its positionshown in Fig. 1 to the position shown in Fig. 13, and as it moves overthe needle in the direction of its arrow, Fig. 13, it engages the end ofthe selected fringe and carries it over to the position shown in Fig.14:. Then it moves back, carrying with it the loose ends, withdrawingthem from the control of the brush, its presser-bar holding the ends inthe hook; \Vhen the hook reaches the position shown in Fig. 15, theselector G moves forward. Its point enters the slot in the bar H. Itthen moves in the direction of its arrow, Fig. 15,

forcing the loop to the right-hand side of theneedle, as shown in Fig.16. The friction-hook I, still retracting, places the ends in the hookof the needle, as shown in Fig. 16. lector then moves down into thespace between the needle and loop and acts as the guide for forming theknot, remaining in the loop until the knot is fully formed. When thefriction-hook reaches the position shown in Fig. 17, the latch e isprojected, inclosing the ends in the hook of the needle. The needle isthen retracted, drawing the ends through the loop and freeing them fromthe frictionhook, asshown in Fig. 18. As the needle descends the presserM moves against the ends,

The seas shown in Fig. 19, and descends with the needle, placingsufficient friction on the ends, so thata tight knot will be formed onthe selector-pin G This pin locates the knot, so that all the knots willbe on a line. After the knot is fully formed and the ends pulled throughthe needle the selector is raised and, as shown in Fig. 20, the arm Kpushes the formed knot down out of the way of the mechanism,which thenrepeats the operation above described to form another knot.

The levers and arms may be modified and the springs may be arranged indifierent positions without departing from my invention, and it will beunderstood that all the cams are so timed as to bring the severalelements of the machine into action at the proper time.
